DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following part will illustrate exemplary embodiments of the present application with reference to the figures, including various details of the embodiments of the present application for a better understanding. The embodiments should be regarded only as exemplary ones. Therefore, those skilled in the art should appreciate that various changes or modifications can be made with respect the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for clarity and conciseness, the descriptions of the known functions and structures are omitted in the descriptions below.

FIG. 1 shows an exemplary system architecture to which a method or apparatus for guiding a voice-packet recording function according to embodiments of the present application may be applied.

As shown in FIG. 1, the system architecture may include terminal devices 101, 102, a network 103 and a server 104. The network 103 serves as a medium for providing communication links between the terminal devices 101, 102 and the server 104. The network 103 may include various connection types, such as wired and wireless communication links, or fiber-optic cables, or the like.

Users may use the terminal devices 101, 102 to interact with the server 104 through the network 103. Various applications, such as a voice interaction application, a map application, a web browser application, a communication application, or the like, may be installed on the terminal devices 101, 102.

The terminal devices 101, 102 may be configured as various electronic devices which support voice recording (that is, are able to collect voice data recorded by a user) and voice broadcasting operations, including, but not limited to, smart phones, tablets, notebook computers, or the like. The apparatus for guiding a voice-packet recording function according to the present application may be provided and run in the above-mentioned server 104. The apparatus may be implemented as a plurality of pieces of software or a plurality of software modules (for example, for providing distributed service), or a single piece of software or a single software module, which is not specifically limited herein. The server 104 may record historical usage behaviors of the map application by the user through a client terminal on the terminal device 101 or 102, and send guidance information of the voice-packet recording function to the client terminal based on the historical usage behaviors.

The server 104 may be configured as a single server or a server group including a plurality of servers. It should be understood that the numbers of the terminal devices, the network, and the server in FIG. 1 are merely schematic. There may be any number of terminal devices, networks and servers as desired for an implementation.

A core idea of the present application includes identifying a user with a voice-packet recording demand using historical map usage behaviors of users; and identifying a scenario where the user with the voice-packet recording demand uses a client terminal, and if the scenario conforms to a preset voice-packet recording scenario, sending guidance information of the voice-packet recording function to the client terminal. That is, the user is identified in terms of demands and scenarios, and only the user with the voice-packet recording demand is guided in the voice-packet recording scenario, thereby reducing excessive disturbance of promotion information in the user. A method according to the present application will be described below in detail with embodiments.

FIG. 2 is a flow chart of a method according to an embodiment of the present application, and as shown in FIG. 2, the method may include the following steps:

in 201, identifying a target user with a voice-packet recording demand using historical map usage behaviors of map users.

Usually, the number of users of an application product, particularly a popular application, is great. If the voice-packet recording function is promoted to all users as in the prior art, users without such a demand are disturbed inevitably.

In this step, the target user is screened, and the adopted ways may include, but not limited to, the following two ways:

the first way: extracting behavior features from the historical map usage behaviors of the map users to obtain feature vectors of the map users; and identifying the map users by a pre-trained first classification model based on the feature vectors of the map users to obtain an identification result whether the map users have the voice-packet recording demand.

In the above-mentioned way, in addition to the behavior feature, the feature vector may further include a basic user portrait. The basic user portrait may include age, gender, work, or the like.

The following description focuses on the behavior feature. In the present application, the extracted behavior feature may include, but not limited to, at least one of a travel-related behavior, a voice usage behavior and a voice packet-related behavior.

The travel-related behavior may include time and position information of at least one of POI retrieval, navigation and location. Usually, a user possibly using the voice-packet recording function may have some features in the map usage behavior, for example, a parent may use the voice-packet recording function to record sounds of his child as a voice packet, which may show positioning data of a kindergarten in the morning and evening, navigation to a training class at weekends, retrieval of a place suitable for play with the child, or the like. For example, a college student may record sounds of himself or his lover as the voice packet, which may show location at a certain college in most time. Therefore, the time and position information of POI retrieval, navigation and location may greatly reflect whether the user is the target user of the voice-packet recording function.

The voice usage behavior may include at least one of the frequency of using a voice function, the time of last usage and the used voice function. For example, users who often use a navigation broadcasting function may be the target users who potentially use the voice-packet recording function. For another example, users who often use a map by means of voice interaction may also be the target users who potentially use the voice-packet recording function.

The voice packet-related behavior includes at least one of the number of times a voice packet is used, the type of the used voice packet, a voice-packet recording state, the time of recording the voice packet most recently and the frequency of accessing a voice-packet recording page. For example, users willing to use various voice packets and having rich voice-packet usage histories are likely to be willing to record the voice packets by themselves. For another example, users who have used the voice-packet recording function but have not recorded new voice packets for a long time may be guided to record new voice packets. For another example, users who do not finishing recording voice packets last time are likely to be guided to finishing the recording of the voice packets.

After extracted for the map user, the behavior feature and the basic user portrait are encoded or mapped to obtain corresponding feature vectors which are further spliced to obtain the feature factor of the map user.

The feature vector of the map user is input into a pre-trained classification model which outputs a classification result based on the feature vector, i.e., whether the map user has the voice-packet recording demand.

When the classification model is trained, positive samples and negative samples may be determined in advance by means of offline visits and telephone return visits; or the positive and negative samples are determined by online sending first guidance information to users in a small range to observe whether the users respond to the first guidance information. Then, behavior features are extracted from historical map usage behaviors of the users of the positive samples to obtain feature vectors of the users of the positive samples, and behavior features are extracted from historical map usage behaviors of the users of the negative samples to obtain feature vectors of the users of the negative samples, thereby training the classification model. The determination way of the feature vectors of the users of the positive and negative samples is consistent with the above-mentioned determination way of the feature vectors of the map users, and is not repeated herein. The classification model may be configured as a support vector machine (SVM), a logistic regression (LR) model, or the like.

The second way: extracting behavior features from seed users in advance to obtain feature vectors of the seed users, and clustering the seed users based on the feature vectors of the seed users to obtain user clusters; extracting behavior features from the historical map usage behaviors of the map users to obtain feature vectors of the map users; determining whether the map users are clustered into the existing user clusters based on the feature vectors of the map users; and identifying the map user clustered into the existing user clusters as the target user with the voice-packet recording demand.

A group of users who have used the voice-packet recording function may be predetermined as the seed users, and the feature vectors may be extracted from these seed users. The extraction way of the feature vectors is the same as the above-mentioned way, and is not repeated. The seed users are clustered based on the feature vectors of the seed users to obtain the user clusters which actually represent some typical user categories, and users in these user categories are likely to use the voice-packet recording function. After each user cluster is obtained, the feature vectors of this category may be calculated uniformly, whether the map users are clustered into the existing user clusters is determined based on the feature vectors of the map users, and the map user which may be clustered into the existing user clusters belongs to these typical user categories, and is likely to use the voice-packet recording function. The map user which is unable to be clustered into the existing user clusters does not belong to these typical user categories, and is unlikely to use the voice-packet recording function.

The clustering method used in the above-mentioned clustering process is not limited in the present application, and may be a K-means clustering algorithm, an expectation maximization (EM) algorithm, or the like.

In 202, identifying a scenario where the target user uses a client terminal.

The voice-packet recording operation has a harsh environment requirement, is unable to be performed in the environment with high noise, and has a long recording time, which requires the user to have free time. However, since the users have different behavior rules, not all the users are suitable for being guided in the same scenario, and therefore, an existing way of performing a pushing operation for all the users at the same time is not correct, and is prone to disturb the users excessively. In view of this, a scenario identification mechanism is introduced in the embodiment of the present application.

In this step, a simple scenario identification way may be adopted to judge whether the current time and position of usage of the client terminal by the target user belong to the preset voice-packet recording scenario. For example, whether the current time is eight in the evening or the weekend and whether the user is positioned at home are judged.

However, in addition to the above-mentioned simple judgment with time and position as rules, the usage of information of the scenario is required to be richer and deeper in consideration of the complexity of behavior habits of the users. Therefore, the present application provides a preferred way of identifying the scenario, including:

acquiring information of the scenario where the target user uses the client terminal, and identifying the information of the scenario by a pre-trained second classification model to obtain an identification result whether the information of the scenario conforms to the voice-packet recording scenario. The acquired information of the scenario may include one or any combination of the following information:

time information and position information of usage of the client terminal by the target user, the time of last POI retrieval, the time of last navigation, location at a resident position, the voice-packet recording state, the time of recording the voice packet most recently, response information of historical first guidance information, or the like.

When the second classification model is trained, positive samples and negative samples may be determined by online sending the first guidance information to users in a small range to observe whether the users respond to the first guidance information. Then, information of scenarios of the users of the positive and negative samples is acquired to train the classification model. The acquisition way of the information of the scenarios of the users of the positive and negative samples is consistent with the above-mentioned acquisition way of the information of the scenario of the target user.

In addition, it should be noted that in the present embodiment, the terms “first” and “second” in the terms “first classification model”, “second classification model”, “first guidance information”, “second guidance information”, or the like, do not have the meaning of a number, an order, or the like, but merely make a name distinction.

In 203, if the identified scenario conforms to the voice-packet recording scenario, sending first guidance information of the voice-packet recording function to the client terminal.

The first guidance information may be one or any combination of a text, a picture, a page component, a link, or the like. The user may conveniently access a voice-packet recording page to record voices with the first guidance information. For example, as shown in FIG. 3, a combination of the component and the text, the picture and the link may be displayed on an interface of the client terminal to show the first guidance information. When the user clicks “click recording” in the interface, the interface is jumped to the voice-packet recording page.

In 204, tracking and recording the voice-packet recording state of the user after acquiring the event of recording the voice packet by the user.

The tracking and recording operations of the voice-packet recording state of the user may be used for both the later identification of the user demand and the scenario (i.e., an updating operation of the behavior features of the user and the scenario features) and execution of step 205.

In 205, sending second guidance information to the user according to the voice-packet recording state of the user.

In the application, different documents may be pre-configured according to different recording states, and text information, voice information, or the like, of the corresponding document are sent to the user as the second guidance information according to the voice-packet recording state of the user.

For example, if the user still has 5 sentences to be recorded, a voice “victory is in sight, go for it” may be sent to the user. If the user finishes the recording operation, voices “great, recording is finished, and the voice packet may be downloaded after 15 minutes”, or the like, may be sent to the user. Such guidance information may encourage the user, assist a child, or the like, in finishing the recording operation at once, and also enable users who are not familiar with the recording process to learn the next step.

The above is a detailed description of the method according to the present application. An apparatus according to the present application will be described below in detail in conjunction with an embodiment.

FIG. 4 is a structural diagram of an apparatus according to the embodiment of the present application, and as shown in FIG. 4, the apparatus may include a demand identifying unit 01, a scenario identifying unit 02 and a first guiding unit 03, and may further include a recording tracking unit 04 and a second guiding unit 05. The main functions of each constitutional unit are as follows.

The demand identifying unit 01 is configured to identify a target user with a voice-packet recording demand using historical map usage behaviors of map users.

The demand identifying unit 01 may adopt, but not limited to, the two following ways:

the first way: extracting behavior features from the historical map usage behaviors of the map users to obtain feature vectors of the map users; and identifying the map users by a pre-trained first classification model based on the feature vectors of the map users to obtain an identification result whether the map users have the voice-packet recording demand.

The second way: extracting behavior features from seed users in advance to obtain feature vectors of the seed users, and clustering the seed users based on the feature vectors of the seed users to obtain user clusters; extracting behavior features from the historical map usage behaviors of the map users to obtain feature vectors of the map users; determining whether the map users are clustered into the existing user clusters based on the feature vectors of the map users; and identifying the map user clustered into the existing user clusters as the target user with the voice-packet recording demand.

In the above-mentioned way, in addition to the behavior feature, the feature vector may further include a basic user portrait. The basic user portrait may include age, gender, work, or the like.

Then, behavior features are extracted from historical map usage behaviors of the users of the positive samples to obtain feature vectors of the users of the positive samples, and behavior features are extracted from historical map usage behaviors of the users of the negative samples to obtain feature vectors of the users of the negative samples, thereby training the classification model to obtain the first classification model.

Specifically, the scenario identifying unit 02 may acquire information of the scenario where the target user uses the client terminal, and identify the information of the scenario by a pre-trained second classification model to obtain an identification result whether the information of the scenario conforms to the voice-packet recording scenario.

Correspondingly, the apparatus may further include a second model training unit (not shown) configured to acquire training samples; for example, positive samples and negative samples may be determined by online sending the first guidance information to users in a small range to observe whether the users respond to the first guidance information. Then, information of scenarios of the users of the positive and negative samples is acquired to train the classification model to obtain the second classification model.

The first guidance information may be one or any combination of a text, a picture, a page component, a link, or the like. The user may conveniently access a voice-packet recording page to record voices with the first guidance information.

The recording tracking unit 04 is configured to track and record the voice-packet recording state of the user after acquiring the event of recording the voice packet by the user.

The second guiding unit 05 is configured to send second guidance information to the user according to the voice-packet recording state of the user.
